A detailed explanation of the surface area of a rectangular prism. It might have been better if there had been more description of the concept of surface area in general and how to find the area of a rectangle.

Volume of Rectangular Prism
(2:57)
The real-life example is good but I think the video would be better if there was more explanation as to why the product of the length, width, and height gives us the volume.
